Rich snippets – blog errors

Hi,

Few questions about rich snippets:

1. When testing rich snippets for my Highend blog posts, I get this errors:

author
A value for the author field is required.
canceldatePublished
A value for the datePublished field is required.
cancelimage
A value for the image field is required.
cancelpublisher
A value for the publisher field is required.
warningdateModified
The dateModified field is recommended. Please provide a value if available.
warningmainEntityOfPage
The mainEntityOfPage field is recommended. Please provide a value if available.

Also, at the end of URL, there gets post-68 (I’m not sure that is propper tagging). You can also try your blog also:
http://hb-themes.com/themes/highend/presentation/2014/03/31/fullwidth-post with https://search.google.com/structured-data/testing-tool/.

2. Do you have plans to implement breadcrumbs or products in later theme updates?

3. What is this WP Header for? Do we get anything if we add /header-inner at the end of URL structure?
